METHOD OF MOUNTING PORTRAITS.

SPECIFICATION formingpart of Letters Patent NO. 401,441, dated April 16, 1889. Application filed'April 19, 188B. $cria1 No. 271,206. (Nomodeh) To all whom it may concern:

Be it known that I, PHILIP G. KRAMER, J r., a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in the Method of Mounting Portraits; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

. lhis invention relates to the method of mounting or finishing portraits or photographs, the object being to give such portraits when finished a more life-like appearance than as heretofore practiced, making, also, a more attractive picture; and the invention consists in first tinting that port-ion of the picture intended to be exposed, then coat-ing the background or. surface of the card surrounding the picture with a solution of glue or some suitable adhesive agent. Then I sprinkle over the adhesive agent a coating of hematite, or a mixture of hematite and metallic bronze, a sufficient amount being used to form a coating of glitter over the adhesive agent. As soon as the cement has dried or set, all loose particles of the hematite and metallic bronze are removed by meansof abrush or like article, thus forming a brilliant and attractive background and giving the portrait a life-like appearance.

The several steps taken will be hereinafter fully set forth, and the essential features pointed out particularly in the claims.

In the accompanying drawings, forming a part of this specification, Figure 1 is a view illustrating my invention. The dotted background represents the metallic flakes. Fig. 2 is a cross-section of Fig. 1, taken on the dotted line a:

In the drawings, C represents the common card-board, on which is mounted, as is the common practice, the portrait D. The front face of the card-board, up to and along the object or portrait line a, iscoated with a cement or adhesive agent. I use for cementing common glue and gum-arabic, the latter being cut with alcohol, and the parts used being about equal as to the glue and gum-arabic. The solution must be thin and used while Warm. As soon as the adhesive agent is applied a coating of flaked hematite, or flaked hematite and flaked metallic bronze, is sprinkled over the surface coated with the adhesive agent. hen the cement has set, the loose particles or flakes are removed by means of a brush or like article, leaving the flaked surface 13.

\Vhen using the flaked hematite and flaked metallic bronze, they are mixed together before applying and while in a dry condition. To one part of hematite I use about onetwentieth part of metallic bronze. The metallic bronze deadens or reduces the glitter of the hematite, thereby giving a softer and better appearance to the background.

hen tinting or coloring the portrait D, the tinting should be first applied, then the adhesive agent over the untinted surface. Then the flaked material should be sprinkled over the adhesive agent, so as to form an even coating.

In general practice I use along the objectline a a finer grade of the metallic flakes, so as to give a more uniform and even finish around the portrait.

The tinting is accomplished with a brush, as in the common practice, and will therefore need no special mention.

Having thus fully set forth my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The herein-described method of mounting pictures, which consists in first tinting the portrait, then applying liquid cement over the card surroundingthe portrait, and then sprinkling on said cemented surface a covering of flaked hematite and flaked metallic bronze, as and for the purposes specified.

2. The method of finishing portraits, which method consists in first tinting or coloring the portrait, then coating the untinted portion or front surface of the picture with cement, and then sprinkling on the cemented surface a coating of flaked hematite, as and for the purpose specified.

In testimony whereof I afflx my signature in 100 presence of two witnesses.
